Equip the entire country of 24 million household with identical fridge freezers

and on average only 1/24 of them would be requiring power per one hour period.

They don't all turn on at precisely 17:32:06 and each present 4.8kW load to the

grid.

So for a typical A++ rated fridge freezer your entire demand control capability

for one hour is 600MW for an installed base of 24 million fridge freezers.

Install the same overall level of demand control for a few hundred commercial or

industrial consumers and the payback for the customer is much quicker, the costs

of implementing it are significantly lower for all parties, the customer sees

100% return on their invested capital in five years or so. The infrastructure to

support this demand control exists now and has done for a few decades.. *Above

all it requires no investment from anyone but the customer.

All smart metering schemes will require wiring changes/appliance

changes/infrastructure changes. *The benefit to the domestic end user is near

zero. *The benefit to grid system operator and distribution network operator is

near zero. *The only ones that benefit are the parasites supplying and

installing the appliances / equipment.

If the government keep their stupid fingers out, it won't be long before appliances with this feature are available for an extra £5.

No you'll be entered into a free prize draw....

*An 8 bit cpu can respond to frequency,

Not that easily,

Rubbish.

and I doubt using that method would be very successful.
Far better to have teh aplience switched off on demand from the suplier than wait for the frequency to alter which would be difficult to measure cheaply.

Be silly to have to measure the frequency of every device.

Be even silier to have to have power line comms hardware and asociated
software stack running on every device.
